[PATCH 1/5] powerpc/fadump: Remove set but not used variable 'elf'

[zhengbin <zhengbin13@huawei.com>]

Fixes gcc '-Wunused-but-set-variable' warning:

arch/powerpc/kernel/fadump.c: In function fadump_update_elfcore_header:
arch/powerpc/kernel/fadump.c:790:17: warning: variable elf set but not used [-Wunused-but-set-variable]

It is introduced by commit ebaeb5ae2437 ("fadump:
Convert firmware-assisted cpu state dump data into elf notes."),
but never used, so remove it.
